When UBports launch their first stable Ubuntu Touch OTA update, they said that it runs on all officially supported Ubuntu Phone devices, except Nexus 4 and Nexus 5 devices, but since most of the team’s members are Nexus 5 owners, it looks like they were working lately on upgrading the Nexus 5 to the Ubuntu 16.04 base. Yes, you’re reading it right, Ubuntu 16.04-based Ubuntu Touch update is coming, and it won’t be long until you can install it on your devices, which now run Canonical’s old Ubuntu 15.04 base. That’s why UBports weren’t able to release the promised OTA-2 update to the stable channels.
